When the emergency stop device is actuated, e.g. by a safety door, the enable
paths of the safety module are interrupted. This leads to the removal of the STO
signals (X2B.2 and 4) and thus to the energy shutdown of the motor.
The safety module performs a consistency check of all signal paths via test signals
(OSSD).
